This movie was probably made in the late 80's, early 90's. I can't remember very much about it because I saw it as a kid and have spent years wondering what it was. So here it goes- I think there is a research lab doing experiments on people. The main female's dad is turned into a giant centipede, which happens towards the end. There is a monster/mutant that has some sort of eye or something in the middle of his forehead that gives him power. At one point it gets ripped out and is being dangled over an acid pool or something. I think he is good though because there are other mutants like him that are the bad guys. That's all I can think of. Hope someone knows what I'm talking about.
